BUTTON-CLASP.

Specification of Letters Patent.

Patented Mar. 29, 1910.

Application filed July 13, 1909. Serial No. 507,399.

Clasps, of which the following is a specification.

My invention relates to button clasps but more particularly to themanner of fastening the extremity of the button tab.

The object of my invention is to provide a device of this character inwhich the tab is permanently secured without resorting to the expedientof sewing or stitchmg.

I/Vith this and other objects in view my invention consists in thedetails of construction and manner of operation fully set forth in thefollowing description and accompanying drawings in which like referencecharacters refer to corresponding parts.

In the drawings: Figure 1 is a front view of my improved clasp a part ofthe supporting webbing being broken away; 2, a central vertical sectionof Fig. 1; Fig.8, an enlarged fragmentary view of the pivotal connectionshown in Fig. 2; Fig. 4, a front view of a modification; Fig. 5, anenlarged fragmentary view of the pivotal connection shown in Fig. 4;;Fig. 6, a front view of a further modification; Fig. 7, an enlargedfragmentary View of the pivotal connection shown in Fig. 6; Fi s. 8 and9, enlarged fragmentary views 0' the pivotal connections of furthermodifications, and Fig. 10, a sectional view of the parts during theprocess of assembling the modification shown in Fig. 9.

Referring to Figs. 1, 2 and 3 the clasp, which is shown loosely mountedon the looped extremity of the supportlng strap A, consists of the baseloop B, button loop C and button tab D which latter is made of fabricand carries a button E. The base loop B, which is made of wire, isprovided with an opening 1 for the passage of the supporting strap A andis also provided with a lower side 2. The button loop C, which 15 madeof sheet metal, is provided at its upper extremity with a projectingtongue or strap 3 which latter is bent or curled around the lower side 2of the base 100 B to form a pivotal bearing inside of which theextremity l of the button tab D is folded around the lower side 2 of thebase loop B and 1s firmly secured by being pinched between the edge 5 ofthe tongue 3 and the body portion of the button loop C. The folding ofthe extremity 4: of the tab around the lower side 2 of the base loop notonly assists in fastening the tab but also forms a bushing of fabricmaterial between the lower side 2 and the curled tongue 3 which gives atighter bearing and a more desirable pivotal action than the metalsurface presented by the curled tongue.

Referring to the modification shown in Figs. 4 and 5 the sheet metalbase loop B is provided on its underside with a projecting tongue orstrap (3 having an edge 7. The tongue (3 is curled around the top side 8of the wire button loop C forming a pivotal bearing. The extremityi) ofthe tab 1) is firmly secured by being pinched between the edge 7 and thefront face portion of the base loop B. The button end of the tab ispassed rearwardly in under the bearing and down the rear side of theloop G, and the button E cooperates with the button loop in a well knownmanner. \Vhen the tab is fastened to the front side of the clasp asshown in this modification the threading of the button end in under thebearing serves to relieve the strain on the confined extremity.

Referring to the modification shown in Figs. 6 and 7 the lower side 10of the wire base loop B is pivotally connected to the top side 11 of thebutton loop C by means of the sheet metal binder or strap 12. Theopposite extremities 13 and 14 of the binder are curled around the sides10 and 11 respectively of the base and button loops their respectiveedges meeting substantially to grip or pinch the extremity 15 of the tabD between them. The button end of the tab is passed in under the binderand down the rear side of the loop in the preceding modification.

In Fig. 9 the lower side 16 of the wire base loop B is pivotallyconnected to the top side 17 of the button loop C by means of the binder18 which is shown reversed so as to fasten the extremity of the tab D onthe rear instead of the front side of the clasp as in Figs. 1 and 2. Theextremities or straps 19 and 9.0 of the binder are made sufficientlylong to enable them to overlap and compress or grip the extremity 21 ofthe tab between them. By arranging the extremities of the binder so thatthe edge 22 of the upper prollO jccting strap is on the outside, the tabwill pass over this edge which serves not only to keep the tab uniformlyspread but also to relieve the strain upon the extremity which isconfined between the straps.

.In Fig. 10 the lower side 23 of the'wire base loop B is pivotallyconnected to the top side 24 of the button loop O by means of the binder25. In assembling the parts the binder is first bent up as shown in Fig.10 to form a pair of open bearings into which is placed respectively thelower side 23 of the base loop and-the top side 24 of the button loop,the extremity 29 of the tab l)* being first placed in the upper bearingso as to lie in under the lower side 23 of the baseloop. The straps arethen bent to close the bearings and if desired the tab may be grippedbetween the edge 28 of the upwardly projecting strap 27 and the lowerside 23 of the base loop.

It will be observed that my improved manner of fastening the tab notonly saves labor in eliminating the sewing, which is a much slowermethod, but also enables a shorter tab to be employed than in the casewhere the extremity of the latter is folded and stitched around somemember of the clasp or to the back of the supporting strap. It will befurther observed that the end of the tab is not only confined butconcealed within the bearing thereby preventing raveling or fraying, andthat the edge not only assists in holding the tab but also keeps thesame uniformly spread.

Having now disclosed my invention as embodied in the devices abovedescribed such modifications as may fairly come within the scope of theappended claims will readily suggest themselves.

Having now described my invention what I desire to claim and protect byLetters Patent is:

l. A button clasp having two members provided with adjacent cross bars,a sheet metal binder bent around said cross bars and a fabric tab havingits extremity gripped between the extremities of said binder.

2. A button clasp comprising an attaching loop and a button loop, one ofsaid loops being provided with a cross bar and the other with aprojecting sheet metal strap which is folded around said cross bar toform a pivotal bearing and a fabric button tab having its extremityconfined in under the edge of said strap.
